2015 GM-E39A question with fueling on none flex app.
Why oh Why GM would you put virtual math coefficients on a non flex fuel vehicle, sorry rant before question.
I have been overthinking this way to much i believe because i am new to tuning ,but i have a 2014/15 2.0ltg twin scroll turbo malibu with the awesome GM-E39A 12653998 (joke maybe) but when looking at spark advance fuel its shows Flex Fuel Spark: Flex Fuel (E85) modifier to the main spark tables, PE/COT Spark Advance Correction (Gasoline) vs. RPM vs. EQ Ratio: This table is used to modify spark advance when in PE or COT modes. It adds to the current spark advance. and of course PE/COT Spark Advance Correction Mult vs. MAP: The multiplier is used to modify the PE/COT spark in relation to MAP. Now for Stoich AFR reads as is 13.97-8.97 0% alcohol - 100% of course. Now even with the Flex being disabled it uses a virtual Fuel Sensor, [ECM] 20220 - Flex Fuel Sensor: If enabled, a fuel composition sensor is fitted. (If disabled, virtual fuel composition calculations are used.) So for the spark tables what would be the theoretical way to go about this. Flex fuel mult zeroed out in stock and alcohol.
Like i say probably over thinking it but yeah could use some help of dumming it down lmao.
Thx in advance.Attachment 161318
